Compact but Powerful
I bought this amp to put in a bass boat and I was very surprised when I opened the box. It's a very small amp and I had no problem mounting it where I wanted. It runs cool and powers my speakers with ease. My birth sheet said 507 watts.

Ole school
The ease of use and install, the look and design are awesome, the output is consistent and clear. I matched it with the rest of my Rockford Fosgate stereo. I am happy with it

AWESOME!
This amp is AWESOME! Sounds great! Comes with a certification saying my serial unit was tested to 536 RMS. Would highly recommend.

Good sound, small package
I have this amp pushing a pair of RF 262s and a pair of RF 282s. Much better sound than my previous MB Quart amp (and that one didn't sound bad either). Time will tell how it holds out - only 3 stars on durability because I have only had it for a few week no, but 0 issues.

Real Good Amp
It's my first marine amplifier. I used it whole summer. Can drive it at max without over heating. The longer period I used it is about three hours at maximum volume and the battery is still good for start the motor. Use it bridge with two eight inches Rockford Fosgate M282.
I Really think it's a quality amp and would buy it again.
